振动焊接 vibratory welding / vibratory welding

在焊接过程中，对构件注入振动外场，以提高焊接接头品质的焊接工艺。

In the welding process, a vibration external field is applied to the component to improve the quality of the welded joint.

形成振动外场的振动器；对质量偏心旋转式激振器，其输出参数包括功率（单位为W）、偏心距（%） 与转速（单位为r/min）；对质量块往复式激振器，其输出参数包括功率（单位为W）、质量块质量（单 位为kg）、振动频率（单位为Hz）和质量块行程（单位为mm）。

Vibrator generating an external vibration field; for an eccentric mass rotary exciter, its output parameters include power (in W), eccentricity (in %), and rotational speed (in r/min); for a reciprocating mass exciter, its output parameters include power (in W), mass of the mass block (in kg), vibration frequency (in Hz), and stroke of the mass block (in mm).

熔池振幅与熔池振动传感器 pool vibration amplitude & pool vibration sensor / molten pool vibration amplitude & molten pool vibration sensor

熔池振动传感器是设在熔池周边，能在焊接过程连续有效工作10 s 以上的专用加速度传感器。 振动焊接的熔池振幅：2 个跨焊缝放置的传感器所测得的振动加速度平均值，单位为m/s2；这2 个 传感器放在一个以焊缝为纵轴，横边不大于300 mm、纵边不大于400 mm 矩形对顶角上；该矩形纵边 的最大长度应保证在相同振动控制条件下，单个熔池传感器测得的振幅与期望振幅的偏差不大于 ±15%。

The molten pool vibration sensor is a dedicated acceleration sensor installed around the molten pool, capable of continuous and effective operation for more than 10 seconds during the welding process. The molten pool amplitude in vibration welding refers to the average value of vibration acceleration measured by two sensors placed across the weld seam, expressed in m/s². These two sensors are positioned at opposite corners of a rectangle, with the weld seam serving as the longitudinal axis, where the transverse side does not exceed 300 mm and the longitudinal side does not exceed 400 mm. The maximum length of the longitudinal side of this rectangle shall ensure that, under identical vibration control conditions, the deviation between the amplitude measured by a single molten pool sensor and the expected amplitude does not exceed ±15%.

振动控制传感器 vibration control sensor / vibration control sensor

远离焊缝和激振器，固定在能敏感反映整个焊接过程振动的位置，在整个施焊时间内能不受焊接干 扰，用于振动参数监控的振动加速度传感器。

A vibration acceleration sensor that is positioned away from the weld seam and the vibrator, fixed at a location sensitive to vibrations reflecting the entire welding process, capable of remaining free from welding interference throughout the entire welding duration, and used for monitoring vibration parameters.

振动控制传感器与熔池振动传感器的相关性 correlation between vibration control sensor and / Correlation between vibration control sensor and molten pool vibration sensor

pool vibration sensor 以保证熔池获得稳定的期望振幅为目标，通过试振时的同步对比测量，建立振动控制传感器与熔池 振动传感器对应关系（表或曲线）；其与焊接时序组合形成焊接过程的振动控制方案。 国标久久 www.gb99.cn 免费下载 JB/T 11085—2011 2

Pool Vibration Sensor With the goal of ensuring that the molten pool achieves a stable desired amplitude, establish the corresponding relationship (table or curve) between the vibration control sensor and the pool vibration sensor through synchronous comparative measurement during trial vibration; this, combined with the welding sequence, forms the vibration control scheme for the welding process.

Multiple elastic support points that can avoid the high temperature of the weld seam, ensure the stable placement of the welded components, and facilitate vibration.

Additionally, the molten pool amplitude-time curve, derived from the correlation conversion between the vibration control sensor and the molten pool vibration sensor, is referred to as the a_p−t curve.
